ELECTRIC BREAD TOASTER, v i;

Application filed January 10,1929. Seria1 No. :33 1 654. w

This invention relates generally to bread toasters and has moreparticularly reference to a novel electric bread toaster.

The invention has for an, object the provision of a device of the classmentioned, which is of simple durable construction, desirable in use andefficient in action, and which can be manufactured and sold at areasonable cost.

The invention proposes the use of a hori-- zontal conveyor belt arrangedfor carrying scription and accompanyingdrawings, and

to the appended claimin which the various novelfeatures of the inventionare more particularly set forth. I

In the accompanying drawings forming a material part of this disclosureFig. 1 is a side elevational view of a device constructed according tothis invention.

Fig. 2 is a central vertical sectional View thereof.

Fig. 3 is a fragmentary plan view looking on the shaft of an electricmotor 34.

nuts 26 for lockingthe heating unit in dethe casing in" the vicinity ofthe entrance opening 11 and an idler roller-16 is rotatively mountedwithin the'casing'in'the vicinity of the exit opening '12.

An endless conveyor belt' engages upon these rollers so that a portionof the belt is reachable thru the entrance opening 11 permitting theplacing of slices of bread thereon, and another portion of thebeltserves to drop the toasted slices out from the casing 1O.

A top heating unit 18 has heat insulators 19 on its edges, and screws'20 projecting therefrom and thru slots 21 formed in the casing 10.VVing' nuts122 engage] upon the screws 20 for holding the heat unitsindesired vertical, positions, the said slots 21 being vertical as seen inFig. 1. V A bottom heating unit 23 is also'provided with heat'insulators24am screws 25 projecting therefrom and thru the same slots21 andengaged by wing sired positions,v The top heating unit e11 gages abovethe top strip ofthe conveyor belt 17 and the bottom heating unit engagesbeneath the top strip of the conveyor belt as '7 may be see-n in Fig. 2.r

The shaft 15 is provided with a gear 27 arranged for meshing with theteeth 28 of a wheel 29 fixed upon a shaft 30 rotatively supported instandards 31 attached within the casing 10. A worm wheel 32 is fixed onthe shaft 30 and meshes with a worm pinion 33 The wheel 29 is formedwith a plurality of transverse peripheral grooves 34 and the teeth 28are slidable in these grooves. A- handle 35 connects with each geartooth for moving it from one end to the other end of the grooves. Thecasing '10 is provided with an. opening 36 thru which handles 35project.- In the retracted positions of the handles 35 the gear teeth 28are in line and mesh with the gear 27 and in drawn positions of thehandles 35 theteeth 28 are out of line of the gear 27. v

In operation of the device the motor oper- 14 and the conveyor belt. Thespeed of rotation of the driver roller 14 depends upon the number ofteeth 28 which are in line for engaging against the gear 27. The teeth28 out of line of the gear 27 do not act to rotate the 5 gear 27 andthus reduce the rotation of the driver roller 14. The handles 35 may bemanually moved for moving the teeth 28 for speeding up the conveyor belt17 or for retarding the speed of the conveyor belt ac- 10 cording to thedesired amount that the bread is intended to be toasted.

While I have shown and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to 5 theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claim.

Having thus described my invention, what .0 I claim as new, and desireto secure by United States Letters Patent is In a device of the classdescribed, a casing, an endless conveyor therein, a gear adjacent anopening in the casing and fixed upon a driver shaft, another gearmeshing with said gear and connected for moving said conveyor, the gearteeth of said first gear being slidably mounted so as to be movable to aposition out of mesh with the teeth of said 30 second gear, and rodswithhandl-es attached on the movable gear teeth and extending thru saidopening so that the speed of the conveyor may be adjusted from theexterior of the casing by movements of said handles.

35 In testimony whereof I have affixed my signature. GUSTAV KATER.
